Investigation of specific properties of leather, which allows a comprehensive assessment of the quality of the new material

Abstract

Investigations of the material’s resistance to moisture, sweat, oxidation, and exposure to aggressive media have been carried out. The study of the properties of the experimental leathers of the chromalumotitanium-synthane method and its comparison with the properties of the control leathers of the chromium-zirconate skin treatment method showed that the joint use of tanning compounds of chromium, aluminum and titanium makes it possible to increase water resistance and persistence, resistance to oxidation mixture and skin resistance to aggressive media. It is established that the advantage of the proposed technology of skin treatment in comparison with the traditional method of skin production. The intensity of changes in the structure of the skin depends on the processing technology. It has been revealed that experienced skin has an increased resistance to moisture, sweat, oxidation and exposure to aggressive media.
